Fujitsu tiene un subportátil portable en su línea con el Lifebook U574. Convence en algunos campos, pero no en todos. La lista de pros la lideran el aspecto y el peso y continúa con la duración de la batería, las emisiones, el mantenimiento, y el ClickPad.
El fabricante sigue debiendo al comprador unas cuantas cosas, pero la competencia tampoco las ofrece siempre. La unidad base es demasiado plegable para el uso profesional, lo que no causa una buena impresión de la calidad del caro ultrabook. Las teclas ofrecen poca resuesta, y la calidad de la webcam está más allá de toda descripción. Las grabaciones del micrófono son tan malas como el sonido del altavoz, y la mala pantalla TN con el terrible contraste y los limitados ángulos de visión son un sufrimiento a la vista de la diversidad de pantallas IPS del sector doméstico.
Los compradores que puedan tolerar una pantalla TN podrían optar por el más económico AsusPro Essential PU301LA-RO064G, que trae un mejor teclado (teclado con un punto de presión y caída claros). Los fans de las buenas pantallas deberían evitar el modelo de pruebas e invertir un poco más de dinero en el Toshiba Portégé R30-A-15C con pantalla IPS. Aunque el teclado no sea mucho mejor, el micrófono, la duración de la batería y la diversidad de interfaces son superiores.
